Oth'erobjectsA of the invention will-be pointed out in the 'following description and claims and illustrated.l vthe accompanying drawings, which it is the main object of theV invention disclose, byway rof example, the principle of the 'invention and the best mode, Which has been contemplated, of applying that principle.

A'In the drawings:V

'punching machine of a Well known .form and shows particularly the punch operating 4mech- Figs. 4 and 5 are detail Views showing in difY ferent positions the means for operating the; iloating cam contacts in the card punch.

Fig. 6 is an electrical wiring diagram of the machine which is restricted a. showing necessary to understand the present invention.

Auxiliary keyboard The auxiliary keyboard K maycomprise the structure shown in the patent to O. B. Shafer, No. 2,315,741, issued April 6, 1943, and is also shown on Fig. 2' herein for convenience. The contacts closed; by the keyboardv are shown in the wiring diagramof Fig. 6.

Ini the numerical keyboard there is provided a key I IT for each. of the digits O to 9 inclusive and twor keys, the contacts IZA of which are designated l1 and 12 in Fig. 6 for punching'corresponding X(11) and R(12) index point positions of a card in the punching. machine. Also mounted on this keyboard are supplementary keys which include aV space keyy I I IS (Figg 6). Depression of any key Ill'l` wil-l.' rock a belly crank II9 which, throughv a pin and slot connection, will move av slider |20 towards the left as viewed in Fig. 2. Each of the sliders cooperates at its end with a bail IZLI. to turn the same countercliockwise and the bail in turn will rock a lever |22Y t0, close a pair of bail contacts I"2.3. Bail contacts I23; are common to all ofthe keys I Il' andare closed'V by the depression ot each of said keys. Contacts I'23 are shown in thewiring diagram in Fig. 6 aswell as contacts i214. whichare individual to each key andV are closed. .upon depression of the key. There is one slider IZIJL'for eachV of the keys, which. slider is urged to the left upon depression. of its. associated key and for eachv slider thereisa lever |25 which is rocked to. close the associated pair of contacts |24.. rIfile key IHS operates a similar slider I`2Il and its lever I2-5fcloses two pairs. of contacts not advance of the card one' column. A series of magnets 45 is adapted to select the punches 55 for actuation in the following manner: Associated with each magnet 55 is a pivoted armature 5'!` whosev free end is: connectedv to a rod 58 which,

through a bell crank 59, moves an interposer bar 60 to the left where it cooperates with a punch bar or plate 6I. The forward movement of the interposer bar 66 is adapted to rock a bail 62 pivoted on a rod 63 and which bail is connected to a spring-pressed depending link 64 whose lower free endl is adapted to engage and close the punch magnet cor-itacts-I- This, as will be described in connection with the wiring diagram, closes a circuit through a punch magnet B6 which then attractsv its armature 6l and through a link .and

, y Card punching machine The; card` punching machine used in connecl tion. with the present invention is of thetype shown; in the patent to Fred. Lee andY George F. Daly, No. 1,976,618, dated October 9., 1934, and only so; much` of the operation thereof will be explained as is necessary for an understanding ot itsoperationin connection with the present invention. K n

In general, the punching. mach-ine. (Fig. 1) contains` a feedmagazine 53V from. whichv cards are fed singly fromy the bottoml ofthe magazine isA well known by a picker which feeds the cards to aposition'under punchesY 55 and in the., present machine the carriage ispreferably returned to column 1 of the cardtothe punches preparatory to receiving the perforations effectedby the'rst bell crank connection 52 will draw downwardly on theA pivotedv punch bar or plate 6I to force the selector interposer against the associated punch, thus perforating the card. When the armature 6l is attracted by punch magnet 66 a projection 52a on` the horizontal link 52. closes contacts 65a, which contacts are also shown in Fig..6 of the wiring. diagram. Such contacts are closed after perf'orating the .card and before the punch carriage spaces to the Vnext column position.

In the present machine theenergization of the punch selector magnets 45 of' which there' are twelve., one'for the digit positions'O-Q inclusive and the 11V and 12indexv point positions is under control of the keys of the auxiliary keyboard.

As isy fully shown inthe patent to Lee et` al., No.1,976,618,r when the armature' 61 reaches the limit of its movement to the right the' link 64' will be 'moved'. by'a projection to become disengaged from one of the spring blades of contacts 65to permit such contacts to open, thereby deenergizing'the punch magnet B6' which will then release its armaturek 67,'allowing a spring 68 to rock the plate 6I upwardly and permit the selected interposer 60A to-rise. and thereafter be restored to normal pcsitionbya spring 69..

EscapementA mechanism The escapement mechanisml I5 is shown herein in some detailA in Figs. 4 and 5 but is fully shown and. described in Patents Nos. 1,976,618 and 1,426,223'. vIt will sufice to. say that when an interposer 6.0 is depressed it will rock a bail 'I0 (Fig. 1) attached to a shaft 'lIand therocking of. this shaft wi-ll actuatethe escapement mechanisnr tospace the card carriage a single column. Associated with the escapement. mechanismV are contacts I28a and I2-8b (see Figs. 4, 5, and 6).. These contacts correspond to similarly designated contacts., 128 in Patent No.- 1,976,618. These contacts are normallyv closed but are opened by the escapement. mechanism during the time that the card. carriage is: spacing tothe vnext column position (see Fig, 4). When this column positionhas been reached both of the contacts I28a and |2812 close (see Fig. 5).l Contacts` I28a and I-bV are utilizedin circuits tobe subsequently described in connection with the wiring diagram of Fig. 6.

Punching under control of thecnz'liary keyboard Theoperation of the machine will now he given mainly connection with the wiring diagram of Fig. 6 and there will now be 'described the circuits whichare/joperative' for causing Ypunching of a card under'control of the auxiliary keyboard K. As vpreviously described, when'the digit keysof theauxiliary keyboard are operated the individual contacts 124 (Fig. 2) will'loe closedas well as the bail contacts |23. Closureof contactsy |24 will select punch selector magnetsv 45 forfenergization.' Current is supplied bythe'power supply lines130, and 131 (Figi) and many'of'the'circuit' connections are completed throughcontacts 102 (Figs. 1 and 6) which arewell known -latch contacts in the card punching machine. Y When a key is'depressed a circuit will be completed from the line 131, through latch contacts v102,r wire 138,

VMeans to effect multiple hole'v punching inoneor j more card columns l Occasionally there is ajrequirement for `perforatingacard column withmore than one hole since it is desirable, for, example, to perforatethe digit and also to punch respectively denote X and R..l The present machine incorporates a selectively operated arrangement which controls double (or more) Vpunching for not only a single column but alsofor a plurality of successive columns. Ace cordin'g to the rst .column where multiple punchf ing is tostart, a plug t the desired plug socket .15v (Fig. 6) to the plug thus completing an energizing 1 circuit ,from line 13 1 through latch contacts '102, wire v| 35, floatingcam contacts 128e, wire '1 31, common contact bar 13, brush 12, contact point 14,' plug socket 15, plug connection 1 81 therefrom to, aplug socket 130, through R35@ relay contacts, relay R51, toI line side ,130thus energizing R51 relay at this card columnvposition of the carriage. A hold circuit for the R51 relay is made through the R510. contacts, R58@ contacts now closed, wire 151, through the latch contacts 102 to line side131. Also, through the R35d and R301) contacts the energizing circuit to the multiple punch solenoid 110 is completed through wire |39 togline 130. nergization of the multiple punch solenoid 110 (see Fig. 3,) operates the escapement mechanism'so that the holding `dog is held down to prevent escapement to theJnex-t Column. g -v v The multiple punch solenoid 110moves `abell crank lever 500 clockwise about its pivotstud 50,1, the plunger of the solenoid having a pin 502 engaging in a slot 503 of the bell crank. 'A thrust bar 504 pivoted `at 506 to the bell crank 500 rocks counterclockwise an arm 501 on the escapement (10g Control shaft 508.
